--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- r14-4332-ge40f3301019a521b11bfcc25aeb1388e6da1ca2f should have fixed this exact issue, but I think for gcc 4.8.5 there is another poly_int related issue that currently prevents builds with such system compiler. https://gcc.gnu.org/pipermail/gcc-patches/2023-October/632008.html
